Description

Anchor removal device

[0001] The present invention relates to an anchor removal device, and more particularly, to an anchor removal device capable of removing an anchor body installed on the ground or the like.

[0002] Anchors are generally used to firmly fix structures to walls or the ground. Once an anchor is installed on the ground, it is quite difficult to remove the anchor, and when the anchor comes out of the wall or ground where it is installed, the wall or ground is damaged. Application No. 20-2007-0006719 proposed an anchor bolt remover that was designed to easily pull out the bolt by first removing the sleeve inserted together with the anchor bolt. However, this had the inconvenience of taking a lot of time to remove the anchor bolt because when the push bolt was inserted into the screw formed on the inside of the tab and rotated when removing the anchor, the push bolt pushed the upper part of the anchor bolt, which relatively pushed up the sleeve.

[0003] Accordingly, the present invention aims to provide an anchor removal device that can quickly remove an anchor from the ground while minimizing damage to the ground to which the anchor body is attached.

[0004] The present invention relates to an anchor removal device, and aims to provide an anchor removal device that can quickly remove an anchor installed on a wall or the ground, and further minimize damage to the ground around the anchor installed when removing the anchor.

[0005] To solve the above problem,

[0006] The present invention is to remove an anchor body composed of an upper anchor catch and a main body part at the bottom of the anchor catch that is inserted into the ground or a wall.

[0007] The lower plate where the anchor exposure part is formed;

[0008] One or more lifts installed on the upper surface of the above lower plate and capable of being raised or lowered hydraulically or pneumatically by operating the operating unit with the operating unit;

[0009] A top plate coupled to the upper surface of the above lift and having a head-catching portion formed thereon;

[0010] One or more springs coupled between the upper and lower plates;

[0011] In order to remove an anchor body installed on the ground, the problem is solved by providing an anchor removal device in which a hook body is provided with a fixed hook part formed at the bottom so as to be coupled with an anchor hook part of the anchor body and a head part at the top that is inserted into a head hook part of the upper plate, and when an operating unit is operated using an operating unit to raise and lower a lift installed between upper and lower plates, a spring between the upper and lower plates also expands and the head part of the hook body that is coupled to the fixed hook part of the lower part of the hook body moves upward at the same time so that the anchor body can be removed from the ground, and when the anchor body is completely removed and the operation of the lift is stopped, the lift that has been raised and lowered descends and returns to its original state due to the compressive force of the spring between the upper and lower plates that tries to return to its original state.

[0012] In addition, the present invention provides an anchor removal device that minimizes damage to the ground around the installed anchor body when the anchor body is removed from the ground by inserting a protective plate having a protective exposure opening with a smaller area than the anchor exposure portion of the lower plate or an inclined plate having a bottom exposure opening into the lower surface of the lower plate, thereby minimizing the area exposed around the anchor body and then operating a lift to raise and remove the anchor body.

[0013] The present invention relates to an anchor removal device, which has the advantage of being able to quickly and conveniently remove an anchor body from the ground using a lift, and furthermore, minimizing damage to the ground around the anchor body installed when the anchor body is removed.

[0023] The present invention relates to an anchor removal device,

[0024] In order to remove the anchor body (60) which is installed on the ground or wall and has an anchoring portion (61) at the top,

[0025] A lower plate (40) having an anchor exposure portion (41) formed thereon;

[0026] One or more lifts (20) installed on the upper surface of the lower plate and capable of being raised or lowered hydraulically or pneumatically by operating the operating unit (80);

[0027] A top plate (10) coupled to the upper surface of the above lift and having a head catch (11) formed thereon;

[0028] One or more springs (21) coupled between the upper and lower plates (10, 40);

[0029] In order to remove the anchor body (60) installed on the ground, a hook body (30) having a fixed hook part (32) formed at the bottom so as to be coupled to the anchor hook part (61) of the anchor body and a head part (31) at the top that is inserted into the head hook part (11) of the upper plate (10);

[0030] When the anchor body is removed from the ground, in order to minimize damage to the ground, a protective plate (50) having a protective exposure opening (50a) having a smaller area formed than the anchor exposure portion (41) of the lower plate; or an inclined plate (52) having a bottom exposure opening (52a) having a smaller area formed than the anchor exposure portion of the lower plate; The present invention relates to an anchor removal device in which a protective plate (50) or an inclined plate (52) is inserted into the bottom surface of a lower plate to cover the surrounding ground of the ground where an anchor body exposed to the anchor exposure portion of the lower plate is installed as much as possible, and then a lift (20) installed between the upper and lower plates is raised and lowered using an operating unit (80), and a spring (21) between the upper and lower plates also expands, and the head of a hook body (30) that is caught on a head catch portion (11) of the upper plate moves upward, and the anchor body that is connected to a fixed catch portion (32) at the bottom of the hook body moves upward at the same time to be removed from the ground, and when the anchor body is completely removed and the operation of the lift is stopped, the lift that has been raised and lowered is lowered and restored to its original state due to the restoring compression force of the spring between the upper and lower plates.

[0031] More specifically,

[0032] The above anchor body (60) is composed of an upper anchor catch (61) and a main body (62) provided at the lower end of the anchor catch, inserted into the ground, and partially exposed.

[0033] In addition, the top plate (10) is provided with a head catch (11) and one or more upper installation hooks (12).

[0034] In addition, the lower plate (40) is composed of an anchor exposure portion (41) through which the anchor body (60) can be exposed; a wheel portion (42) installed to facilitate transportation; and one or more lower installation hook portions (43) coupled to the upper surface thereof.

[0035] In addition, one or more lifts (20) are installed between the upper and lower plates (10, 40), and one or more springs are fixedly installed using upper and lower installation hooks (12, 43). The lift is operated by air pressure or hydraulic pressure, but a separate operating unit (80) is provided to apply or cut off power, and when the operating unit (81) is operated using the operating unit, the lift can be raised or lowered by air pressure or hydraulic pressure. Since this is obvious by inference from existing known technologies, it will not be described separately.

[0036] In addition, the hook body (30) is composed of a head portion (31) formed so that the outer diameter thereof is larger than the inner diameter of the head engaging portion (11) of the upper plate so that it can be hooked onto the head engaging portion; and a lower fixed engaging portion (32) formed so that the outer diameter thereof is smaller than the anchor engaging portion (61) of the anchor body so that the anchor engaging portion can be hooked onto it.

[0037] A handle (70) installed on one side of the upper surface of the top plate;

[0038] A protective plate (50) having a protective exposure opening (50a) that can be inserted into the lower surface of the lower plate (40) and has a smaller exposed surface area than the anchor exposure portion (41) of the lower plate;

[0039] Or, it is composed of an inclined plate (52) having a bottom exposure opening (52a) having a smaller exposure area than the anchor exposure portion (41) of the lower plate.

[0040] As an example,

[0041] An anchor body (60) is fixed to the ground, and an anchor catch portion (61) at the top of the anchor body protrudes from the ground where it is installed, and the outer diameter of the anchor catch portion (61) is manufactured to be larger than that of the main body (62). Using the handle portion (70) installed on the upper surface of the upper plate (10) and the wheel portion (42) installed on the lower plate, the device of the present invention is moved to the position where the anchor body is installed so that the anchor catch portion (61) of the anchor body and the surrounding ground where the anchor body (60) is installed are partially exposed through the anchor exposure portion (41) of the lower plate, and then the fixed catch portion (32) at the bottom of the hook body (60) is connected to the anchor catch portion (41), and the head portion (31) at the top is installed by being caught on the head catch portion (11) of the upper plate, and then the operating portion (81) is operated through the operating portion (80) to raise and lower the lift (20). When the lift is raised or lowered, the head of the hook body is raised and lowered together with the upper plate, and the anchor body is removed by moving upward from the ground. At this time, as illustrated in Fig. 7, the spring (21) installed between the upper and lower plates (10, 40) also expands. When the removal of the anchor body is completed, the operation of the operating part is stopped using the operating part, and when the hydraulic or pneumatic pressure gradually weakens, the upper plate is lowered and restored due to the spring's restorative compression force.

[0042] In addition, in order to minimize damage to the ground when the anchor body is removed from the ground, a protective plate (50) having a protective exposure opening (50a) smaller in area than the anchor exposure portion of the lower plate or an inclined plate (52) having a bottom exposure opening (52a) is inserted into the lower surface of the lower plate (40) to minimize exposure of the ground around the anchor body, and then the lift (20) is operated to raise and remove the anchor body, thereby minimizing damage to the ground around the anchor body when the anchor body is removed from the ground.

[0043] Moreover, the inclined plate (52) installed on the bottom surface of the lower plate is designed to level the inclined surface so that the anchor body and the hook body installed on the inclined surface can be vertically fastened to the inclined surface as shown in FIG. 6, and the anchor body and the hook body can be raised and lowered vertically, thereby reducing damage to the surrounding surface compared to when the anchor body is removed in the inclined direction.

[0044] As described above, the present invention has been described with specific details such as specific components and limited embodiments and drawings, but these are provided only to help a more general understanding of the present invention, and the present invention is not limited to the above embodiments, and those with ordinary knowledge in the field to which the present invention pertains can make various modifications and variations from this description.
